After certain embarrassments in the news recently, it seems we could use
Unpatchy, noun: The Apache server that came with your Linux distribution three years ago, and to which you have never applied any security patches.
And from a couple of years ago
Preloopsarian, adjective: In that state of programming innocence in which one has discovered assignment and conditions, but not iteration.
For a classic example of the latter see Chapter 3 of Jon Bentley's Programming Pearls. I regret to say that it is not one of the chapters at the on-line site.
